Well, I do it; and I noticed that sometimes (not always !) when I switch from "composite video" to "component video"... TME by itself switches the audio input from RCA front to RCA rear.
I think I'll also try to better see the Youtube videos where the same problem is discussed; but - being Italian - even though I write it easily, I have problems in understanding what they say in English spoken language.
Then, if nothing resolving would come from here, I'll try with the Hauppauge support (it seems that I rely upon you more than upon them :-))
I just wanted to clarify a few things about the audio inputs with the 1212. If you are not trying to use S/PDIF audio, I do not think your problem can be audio related. On the two different 1212 boxes I use, I can disconnect ALL audio cables, and the 1212 shows a video picture just fine when I select the open front or back RCA inputs, but blank when I select the open S/PDIF.
So for your testing, I suggest you always select the FRONT RCA audio jacks (even without anything connected to them). I suggest this only because you said you did get a good picture on the 1212 while testing the front connections with a composite video input. If you finally solver the problem of blank video form the component inputs, then you can change the audio input selection to the one you actually want to use.
So your problem does seem to be either a bad 1212 box or bad component signal input. I suggest three further tests. First, cold boot the 1212 by removing the power (not just using the on/off button). Second, completely remove the HD Fury form the test by using different component inputs and different component cables. Hopefully you have a DVD or Blu-ray player with component outputs to use for this. You do not need to worry about protected content - all you care about is just seeing the device menu on the 1212 to verify any video on the component inputs.
If an alternate component video source still does not work with the 1212, the last thing I would try is a different power supply. This may be a bit harder for you to find, but just look at the plug for specifications (and pay particular attention to +/- connections on the power jack) My US power plug shows 5V, 2A, with the + on the center pin of the connector. Although it does not specifically SAY DC output, the + certainly indicates it must be 5V DC. Any other 5V DC, 2 amp power supply with the same size connector and + on the center pin should work. You can look for a universal power supply at an electronics supply store.
I have seen quite a few people who found problems with the Hauppauge power supply, and low voltage or weak current could cause some parts of the box to not work correctly and still allow you to see other signs of life. Good luck.
